Games-wise, the Wii U is basically the N64's heir: A nice selection of top-notch games, but if even a few of those don't interest you...then it's time to start digging for hidden gems or just go retro, because there's not much else beyond the big-time titles. Then there's the system itself, which was more of a Switch prototype than its own thing. And, thanks to the gamepad, the Wii U spat in the face of nearly everything that made the Wii easy to market.
So while the Wii U isn't the completely worthless piece of trash it's often made out to be, let's not give it more credit than it deserves, it's no Gamecube or Dreamcast. Those consoles didn't deserve the reception they got, while the Wii U pretty much performed exactly how it should've. It was an extremely misguided, messy, and nigh-impossible to market console with a very good, but also very limited library. No more, no less.
